Oculus DK 2

Oculus began shipping the Oculus DK2 in July 2014. This is a small refinement of the "Crystal Cove" prototype, featuring several key improvements over the first development kit, such as having a higher-resolution (960×1080 per eye) low-persistence OLED display, higher refresh rate, positional tracking, a detachable cable, and the omission of the need for the external control box. A teardown of DK2 revealed that it incorporates a modified Samsung Galaxy Note 3 smartphone display, including the front panel from the device itself. In February 2015, Oculus announced that over 100,000 DK2 units had been shipped up until that point
